Ria de Chelem (Chelem)

Ria de Chelem is a small, shallow, flat lagoon behind Chelem, known for clean water and very smooth conditions that suit flat-water kitesurfing. Because it is a lagoon (not open ocean), the water is described as shallow and calm enough to support beginner learning and freestyle practice when wind conditions line up. Wind at the spot is closely tied to the area’s thermal patterns. The best wind months are February through May, and the spot is especially sought after when the south wind component (“Surada” / southern winds) arrives—conditions that align with the common south/west-to-inland-to-sea flow described in the enrichment. Typical workable wind is described around 15–25 knots, with the strongest period often running from mid-morning into late afternoon. Kitesurfers typically ride freestyle and freeride (and often foil setups), with recommended kite sizes most commonly in the 9 to 14 m² range. Windsurfing can work as flat-water riding, but the shallow depth significantly restricts fin length. Wingfoiling is much more constrained by depth; it’s described as feasible only in specific deeper channels and generally limited overall. Safety-wise, the lagoon includes hazards such as shells, submerged stakes, mangroves, and nearby power lines near the bridge crossing. The guidance is to respect local fishing activity, keep distance from the bridge/power lines, and wear booties. Emergency medical care is not immediately at the lagoon; 911 is the emergency number and major medical services are in Mérida, with quicker access routes via Progreso.
